The James Webb Space Telescope will be the largest space telescope ever built.

The James Webb Space Telescope is on a deep-space mission. And that deep-space mission involves “look[ing] back in time more than 13 billion years to help us understand the formation of galaxies, stars and planets.”

The James Webb Space telescope is currently in construction, but you can see a life-size model at the Maryland Science Center through October 26. Experts will be standing around, happy to answer all your deep-space questions. For free!
